Electrical connector in particular for
Connecting electrical devices
two rocket stages

The invention relates to an electrical connector, and more particularly relates to a connection between Power and / or signal circuits of two successive stages of a guided missile. In detail is directed the invention to a connector of the type mentioned, in which the connection between arranged in housing parts Contacts regardless of making and releasing the

Connection between the housing parts can be produced and is solvable.

Guided missiles and missile systems usually have several successive stages for launch and propulsion and controls in flight. Before the in-flight separation of a rocket stage from the the following, next working stage are usually different power and signal circuits of the two Steps electrically connected to each other. For the ^ connection Special connectors are therefore necessary between the switching devices of two successive stages.

Electrical connectors of the type mentioned must be used: meet very high requirements. These concern U.A. a quick loosening of the connections between each other associated electrical circuits as well as effective protection of the connector contacts from electromagnetic Pulses as they occur in the vicinity of nuclear explosions, especially from radar systems electromagnetic and high-frequency interference, as well as contamination by pollutants present in the environment. This protection must both in the operating state of the connector and after the disconnection and the separation of the rocket stages will be effective · The aforementioned Requirements are met by many known connectors, but there remains one that has not yet been satisfactorily solved Difficulty relating to loosening the connection between the connector parts and the rocket stages.

Most of the known ones used for the stated purpose Connectors contain electrical contacts in the form of plugs and sockets, which - essentially, parallel to the central axis of the connector are aligned. In order to avoid damage to the contacts, they must therefore essentially

909836/0513

brought together parallel to the central axis of the Vrrbinder housing parts and be separated from each other. Furthermore, the known connectors are usually arranged so that the Connection between the housing parts can be produced and released simultaneously with the connection between the contacts is.

When used between two consecutive. Eaketren— stages, the known connectors are usually arranged so that their parting plane is not in the parting plane of the Missile stages runs. The way in which the rocket stages separate from one another is only slight Influence on the loosening of the connection between the housing parts and contacts of the connector »It would be, however Considerable advantages can be achieved if the parting plane of the connector parts were the same as that of the frame steps. In this case, namely, the housing parts of the connector can be directly at the parting plane between the two Steps are arranged. As a result, the devices holding the two rocket stages together can then can also be used to hold the housing parts of the connector together. In addition, would go through Such a measure simplifies and accelerates the assembly of the Eakete.

In known connectors of the type mentioned, the problem mentioned arises from the fact that the connection between the contacts thereof usually by a movement substantially parallel to the central axis of the Connector, must be released and the release of the connection between the contacts on the one hand and the housing parts on the other hand takes place at the same time, so that also, the housing parts are moved apart in the direction mentioned Need to become. However, since a burned-out rocket step with the associated housing part is usually not straight from the next rocket stage and the one to this one

909836/0513

belonging housing part is repelled, move in the parting plane of the rocket stages in mutual contact housing parts of the connector located not apart in a direction parallel to its central axis. at simultaneous loosening of the connection between the housing parts on the one hand and the contacts on the other hand can do that due to the cause explained above tilting of the housing parts relative to one another to damage the Lead contacts of the connector part remaining on the subsequently working rocket stage. Under certain circumstances can therefore cause very serious damage to the contacts mentioned and / or the protective devices provided for them appear.

Such damage to the contacts of the connector part remaining on the subsequently operating rocket stage can have serious consequences because the circuits of the successive rocket stages over the said Connectors are mostly connected in series · Even after the separation of the rocket stages and the associated ones The connector is the connector part remaining on the rocket via the lines connected to it still connected to the circuits of the remaining rocket stages. Damage to the contacts of this connector part can therefore lead to short circuits and failure of the other rocket stages common power and / or Lead signal lines. So although the contacts of on the missile remaining connector part no longer for connection to the circuitry of another Level are required, they must not be damaged under any circumstances. Also, they must continue to face electromagnetic Interference and pollution from the environment are protected. In known connectors of the above However, damage to the contacts url / or the Protective devices for the same are not excluded.

909836/0513

The invention is therefore directed to an electrical connector which can be used in particular for multi-stage missiles, wherein the aforementioned disadvantages and shortcomings of known electrical connectors for connection the circuitry of successive rocket stages and the like are eliminated.

An object of the invention is to provide an electrical connector in which the connection between the contacts the connector parts independently of the establishment and release of the connection between the housings of the connector parts is producible and releasable.

Parting plane 48 in mutual contact »The housing 12 preferably has two essentially identical ones Cavities 50, 52 and one in the middle between them Support web 5 ^ ·· Each cavity 50, 52 contains one Contact arrangement 28 with a number of Kontaktbuclisen. which are embedded in an insert 58 seated in the rear part of the cavity. The open ends of the sleeves 56 are of one of the shielding waveguides surrounded, which is described in detail below. The individual sockets 56 are (not shown) Conductors electrically with their associated circles the respective rocket step connected »In the embodiment shown here, each cavity 50, 52 contains a ver- sliding insulating plug 64 with intermediate contacts inserted therein 62. These each have a socket part for connection to the contact arrangement 30 of the second Connector housing 14 and a plug part 68 for the connection with the contact bushes 56 «The insulating plug 6 * serves the purpose of the second contact arrangement 30 Shorten the distance to be covered and an additional protection of the contact bushes 56 from electromagnetic To ensure disruptions.

In the front part of the cavities. 50 »52 there is a closure flap 70 hinged. in Fig. 3 _s recognizes the flaps 70, as long as the contact assemblies 28,

909836/0513

are separated from one another by a respective spring 71 held in the closed position and when the insert 32 is advanced into the connecting position opened. The flaps 70 serve to protect against electromagnetic interference and prevent the entry of Contaminants from the environment into the cavities 50, 52-

The second connector housing 14 also has two under each other essentially identical cavities 72, 74 which each contain a contact arrangement 30. In the embodiment shown, each cavity 72, 7 * an insulating insert 76 in which the connecting part 38 of the contact arrangement 30 is embedded. The connector preferably has a number of elongated sockets 78, which are connected via conductors (not shown) to circles assigned to them of the rocket stage in question, are. The active contact part 40 of the contact arrangement 30 has a corresponding number of. Contact pins 80 which are embedded in an insulating body 33 of the insert 32 are and protrude forward from it. The pull-out part 42 contains a corresponding number of in extension of the pins 80 protruding backwards from the insulating body, elongated contact pins 82 which are inserted into the associated sockets 78. At her The free ends of the pins 82 each carry a contact piece 84 which, when the insert 32 moves between the connection and the disconnected position constantly in conductive contact with the respectively assigned socket 78 remains. The extended pins 82 with their contact pieces 84 thus receive the electrical connection between them Sockets 78 and the associated active contact pins 80 regardless of the position of the insert 32 upright.

As can be seen in particular in FIG. 7, the movable insert 32 has a pair connected to one another via a support web 87

909836/0513

bound sockets 86, 88, which are slidably guided in the cavities 72, 74 and each have an insulating body 33 included. In the disconnected position shown in FIG the insert 32 is withdrawn so far into the cavities 72, 74 of the housing 14 that the contact pins 80 do not protrude beyond its end face 22. After the housings 12, 14 have been brought together, the contact arrangements can openings 28, 30 are then connected to one another by pulling the insert while stretching the extendable part 42 forward is pushed into the cavities 50, 52. With this movement of the insert, the pins 80 penetrate the sockets 66 of the insulating plug 64 and then push it inwards, until its pins 62 penetrate into the sockets 56. Through this are the sockets 56 then with the contact pin en 80 and electrically connected to the connection sockets 78 via these. The movement of the insert 32 is carried out by means of the following, locking device 34 described in detail.

Immediately prior to the separation of the rocket stages and the two connector housings 12, 14 inserted therein the contact assemblies 28, 30 by sliding the insert 32 separated from each other by the connection and the disconnected position. With the support of a footprint spring 85, the pins 62 are first pulled out of the sockets 56, whereupon then the contact pins 80 from the sockets 66 of the insulating plug ens 64 are pulled. The two housings 12, 14 and all parts belonging to them are then in the separated position of the insert 32 on both sides of the parting plane 48, so that the housings 12, 14 are now moved apart in any direction can without the contact arrangement 28 or its shielding could be damaged in any way.

That in Pig. The first connector housing 12 shown in FIG. 6 preferably has a body 12a formed from cast aluminum,

909836/0513

which contains the two cavities 50, 52. As can be seen in FIG. 8, the flaps 70 are arranged offset inward by a small amount in the cavities 50, 52 and are articulated by means of a hinge pin 92 having hinges 90 so that they come into locking system on the inside of the front wall. The second housing 14 preferably also has a body 14 a cast from aluminum which surrounds the cavities 72, 74 containing the insert 32. Holding parts 94, 95 formed on the outer sides of the cast bodies 12a, 14a are used to fasten the connector housings 12, 14 in the respective rocket stage. In other embodiments, the holding parts 94, 95 can serve to firmly connect the two housings 12, 14 to one another.

The cast body 12a is penetrated by a bore 96 along its central axis. A corresponding bore 98 runs along the central axis of the cast body 14a. After that Insertion of the insert 32 into the cavities 72, 74 is aligned with a bore 99 penetrating the retaining web 87 Bore 98. In the connection position of the two housings 12, 14 relative to one another, the aligned Bores 96, 98 a passage for the locking device 34 for the movements of the insert 32 to Merging and separating the contact arrangements 28, 30-

The locking device 34 shown in detail in FIG. 3 is used to remove the insert 32 from the disconnected position to move into the connection position and then the contact arrangement 28, 30 in mutual connection to hold on. In the embodiment shown, the locking device 34 has rod 100, which is a Has an axial bore 102 extending essentially over the entire length and is displaceable in the bore 96 is guided so that when they are laid together c x · both Housing 12, 14 can be extended into bore 98. That The free end of the rod 100 carries a holding head 104 with it

90983 67 0513

one claw 105 at the end and one protruding backwards thereof Nose 106. A nipple 108 having a thread 110 is screwed into the rear end of the bore 96, in which the rod 100 is guided in a longitudinally displaceable manner. Between the holding head 104 and the nipple 108 is the Rod 100 is surrounded by a sliding bush 112. This is in sliding contact with the inner wall of the bore 96 and is between the front end of the nipple 108 and the front end surface 20 of the housing 12 moveable. The socket 112 has at the front end an enlarged bore 113 with a funnel-shaped to the rear tapering surface 116. This serves as a run-up surface for the nose 106 of the holding head 104 to this for the to press the sliding insert 32 inwardly, as explained in detail below.

The holder 86 guided in the second housing 14 has a nose 114 projecting radially inward into the bore 98. A central tube 117 arranged in the bore 98 has a recess 118 for the engagement of the nose 114. The central tube 117 is displaceably guided in the bore 98 and takes the nose 114 and over it during its movements thus the insert 32 with. At the front end, the central tube 117 has an inwardly protruding edge 120 for the Engagement of the claw 105 on the front end of the holding head 104.

To move the insert 32 from the separated position into the connected position and thus to bring the contact arrangements together 28, 30, the rod 100 is first moved forward in the bore 96 until the claw 105 of the holding head 104 engages on the edge 120 of the central tube 117. Then the rod 100 is withdrawn into the first housing 12, until the nose 106 of the holding head 104 engages in the enlarged bore 113 and the socket 112 at the front end of the Nipple 108 rests. In this position of the rod, the contact arrangements 28, 30 are completely connected to one another.

909836/0513

bound, i.e. the pins 80 have penetrated the sockets 66, the insulating plug 64 is in abutment with the waveguide 60 and the pins 62 are fully in the connection socket 56 penetrated. In this position the rod 100 is secured by means of a lock nut 121.

The two housings 12, 14 can therefore be brought together completely are, however, the insert 32 initially remains in the disconnected position, so that the contact arrangement en 28, are not yet connected. When assembling a rocket, for example, no current flows at first through the connections between the stages until the missile is prepared for launch. To this At this point, the rod 100 can then be moved by hand or by machine in the manner described above to move the insert 32 into the connected position and to bring the contact assemblies 28, 30 together therewith.

The separating device 36 serves to separate the contact arrangements 28, 30 independently of the separation of the connector housing 12, 14 separate from each other. The contact arrangements can thus be moved apart and the connection with it be interrupted before the rocket stages and their associated housings 12, 14 separate from one another. In a preferred embodiment shown in Figures 3 and 3A, the separation means comprises a source or a source Supply line 122 for a pressure medium. The pressure source preferably contains a pyrotechnic charge 124 for Generating a compressed gas. The one designed to generate the largest possible volume of gas in the shortest possible time Charge 124 is in fluid communication with bore 102 of rod 100 via channel 126 so that at The pressurized gas released upon ignition of the charge 124 can flow into the bore 102.

In the front end of the nipple 108, an enlarged chamber 128 is formed through which the rod 100 is guided.

909836/0513

is. As long as the contact arrangements 28, 30 are connected to one another, the front end of the chamber 128 is through the rear surface of the sliding sleeve 1 ^ 2 closed. In the separated position of the insert 32, the socket 112 is in the front part of the bore 96, see above that the chamber 128 is in open flow communication therewith. The bore 102 of the rod 100 is through a passage 130 connected to the chamber 128, so that the compressed gas can flow into this and expand therein.

For separating the interconnected contact assemblies 28, 30, the pyrotechnic charge 124 is ignited and thereby released compressed gas flows into the chamber 128. The expanding in the chamber 128 pressurized gas pushes the sleeve 112 forward, so that the inclined surface 116 of the enlarged bore 113 runs up against the nose 106 of the holding head 104 and compresses it radially in order to release the claw 105 from the inner edge 120 of the central tube 117. The sleeve 112 is then pushed further forward by the compressed gas expanding in the chamber 128 and in the bore 96 until it attaches to the front end of the central tube 117 and pushes it back into the bore 98 in order to move the insert 32 into the separated position. The central tube 117 pushed back completely into the bore 98 then comes into engagement with the cast body 14a of the housing 14 via a slotted spring ring 132 or the like, so that it cannot inadvertently advance back into the bore 96. The contact arrangements 28, 30 are thus completely separated from one another, and the contact arrangement 30 is withdrawn beyond the separation plane 48 into the housing 14. The two housings 12, 14 can now be separated from one another together with the frame steps in any direction without the contact arrangement 28 being influenced thereby. When the contact arrangement 30 is withdrawn from the housing 12, the flaps 70 close automatically in order to shut off the cavities 50, 52 and the contact arrangement

909836/051 3

28 to protect against contamination from the environment during the subsequent separation of the two housings 12, 14 from one another.

The second housing 14 contains a contact arrangement 30 which has essentially the same structure as in the embodiment according to FIGS. 3 and 3A. The contact arrangement 28 accommodated in the first housing 12 ' has an insert 58 * which is composed of two insulating bodies 134-135 and an insertion seal 136 connected to them in a single stage. A number of connection sockets 138 inserted into the insert 58 * are surrounded on the inlet side by a waveguide integral with the housing 12 *. In this embodiment , the insulating plug 64 provided in the housing 12 according to FIGS. 3 and 3A is missing, so that the housing 12 'can be made shorter. The actuation of the insert 32 to bring the contact assemblies 28 and 30 together takes place in essentially the same manner as described above.

The locking device 34 'of the embodiment according to FIGS. 4 and 4A has a rod 142 which is guided longitudinally displaceably in the bore 96 and can be extended into the bore 98 of the second housing 14 . The rod 14-2 has an external thread and is screwed with this into a nut 144 which has a connector-shaped extension 145 which can be inserted into the rear end of the bore. However, this is only introduced into the bore 96 when the contact arrangements 28, 30 are completely connected to one another . The vorstreckbare free end of the rod 142 carries a retaining head 146 with inwardly directed Έ .auen 148 and a run-on part 150th

909836/0513
